heat conduction cylinder wallThis calculation determines the heat transfer through a cylinder wall by conduction

 
 
 
 

\(\large{ Q_c = \frac { 2 \; \pi \; k \; l \; \left( T_1 \;-\; T_2 \right) }  { ln \; \left( \frac {r_2 }{ r_1 } \right) } }\)

Where:

\(\large{ Q_c }\) = heat transfer by conduction

\(\large{ l }\) = length of the material

\(\large{ r_1 }\) = radius to inside wall

\(\large{ r_2 }\) = radius to outside wall

\(\large{ T_1 }\) = temperature of one surface of the wall

\(\large{ T_2 }\) = temperature of the other surface of the wall

\(\large{ k }\) = thermal conductivity
